The invention provides core-sheath filaments. The core-sheath filaments have a core composed of diene-based rubber crosslinked by multifunctional acrylate, thereby forming an adhesive with excellent high-temperature performance. The adhesive composition exhibits outstanding durability against oxygen and moisture, low and stable dielectric properties, and superior high-temperature resistance. The invention also provides a preparation method of the core-sheath filaments and application of such core-sheath filaments with a core of diene-based rubber crosslinked by multifunctional acrylate.
